The document outlines the evolution of computer generations from the first to the fifth generation. It details key characteristics such as the transition from vacuum tubes to transistors and then to microprocessors, highlighting size reduction and increased processing speeds. The fifth generation focuses on artificial intelligence and systems capable of natural language processing.

1. Computer
By-Truptimayee Nanda

2. First Generation (1GL)(1946)
 can perform thousands of calculation in few hours.
 Large in size.
 This generation of computer use vacuum tube for
processing.
 Ex. ENIAC, UNIVAC

3. 2ND Generation(1950)
 In 1950,this generation of computer introduced
 Use transistor in the place of vacuum tube.
 Smaller than 1st generation computer.
 Ex.IBM 1620

4. 3rd Generation(1960)
 Use Integrated Circuit in place of transistor .
 Smaller in size than 2nd generation computer.
 Processing faster than 2nd generation computer.
 Ex-IBM 360,

5. 4TH Generation(1971)
 Use microprocessor.
 SIZE IS VERY SMALL.
 Internet was evolved during this generation.
 Ex Apple,IBM

6. 5th Generation
 Artificial Intelligence is used.
 These systems respond to natural language and
capable of taking decision by self.
